Hey guys (and gals), please don't go out and try out an A7 series Sony camera. And don't bring along your Pentax K7/5/3 to compare it to. It'll make you cry or drool - one or the other.
I and a friend bought lunch for another club member to show us his Sony collection, he has the A7R, the A7S and all the native lenses, almost. They, with the FF sensor, are a little smaller and lighter than the K3. And the zoom lenses aren't a bad size, even the 70-200, because they are all F4. Unlike Pentax, none of the Sony lenses are weather resistant, altho the A7 bodies are supposed to be. I have more faith in my Pentax bodies because they've been at the game longer.
But Pentax used to be the maker of small SLR bodies - now its Sony - thats the first thought that occurred to me. Pentax still makes better lenses IMO, but i sure like the size and weight of the A7 bodies. The bizarre A7S appeals to me :-) There's just no accounting for taste.
The time for Pentax to get into the mirrorless game - more than the Q, is NOW, in my probably erroneous opinion.
Have some great holidays everyone!!!
